B-complex and Hardwood Propagation
I had the worst luck with propagating plants by either hardwood or softwood cuttings. I've tried crape myrtle, photinia, texas sage, butterfly bush, etc., and it seems like everything has failed.
I've had success, however, after I started moistening the growing medium with b-complex and water mixed in a blender. Even my photinias which had rotted came back to life after I removed them from the medium, knives off the decay, then soaked the ends of the hardwood in the mixture for 12 hours. I noticed a small amount of cane sugar also helped.
Has anyone else found this? What's the science behind it, if anything?
